Tesla to open‑source Model S and Model X designs as production ends

Tesla announced that it intends to release the design files, engineering documentation and software code for its Model S and Model X electric vehicles as open source. The plan follows the company’s decision to cease production of both models in the first or second quarter of 2026, with the Fremont plant halting assembly in late March 2026 and South Korean orders closing on 31 March 2026. Production lines are being repurposed for new projects such as the Optimus humanoid robot and the Cybercab autonomous vehicle.

Elon Musk referenced the earlier open‑source of the original Roadster in 2023, indicating that the upcoming release will give owners, independent repair shops and developers access to CAD drawings, diagnostic tools and battery‑control code. The move is expected to lower maintenance costs, enable third‑party repairs and allow the broader engineering community to study Tesla’s battery and software architecture.

No formal corporate statement has confirmed the timeline, and the report is based on speculation circulating on social media and industry sources.
